Abstract
A conventional passenger vehicle has a lower deck and an upper deck on both sides of its aisle to double seating areas. Each deck has a ceiling and seat heights about the same as in sedans, hence minimizes the increase of vehicle height. Both decks are divided into seating sections with partition walls, and in a seating section each deck contains only a row of reclining seats. A ladder equips on each upper seating cell. Each seat has a footrest mounted separately on the partition wall in front of the seat for sitting comfort and forming a bed with the seat. The footrest can place at a higher elevation to use as a table and placed in a vertical storage position, providing more leg room for the seat. Some seating sections on the lower deck may mount two rows of non-reclinable seats to increase the vehicle capacity.
Claims13
A passenger transportation vehicle has at least a walking aisle along its length, and a lower deck and an upper deck on both sides of each aisle to increase seating area, and each deck height is for sitting only to minimize an increase of a vehicle height, and some sections of the lower deck provide non-reclinable seats to increase the numbers of seats in the passenger transportation vehicle, and both decks are divided into seating sections, along the aisles, and each seating section is divided by the aisles into multiple cells on each of the upper and lower deck, and the seating cells with reclining seats are separated with vertical partition walls, and each seating cell contains one row of the reclining seats mounted on the horizontal deck close to the rear partition wall, facing forward, and each reclining seat contains a base frame supported by a pair of horizontally laid linear slides mounted on a footing frame anchored to the deck, a seatback supported by the base frame on a seatback hinge and connected to a stationary structure behind the reclining seat with a pair of tipping bars, enabling to slide on the linear slides when reclining, a cushion supported by the base frame on a cushion hinge, and a pair of links connecting both seatback and cushion to tilt the cushion at different paces when the seatback reclining to achieve sitting comfort and place the cushion horizontally to line up with the seatback when the seatback fully reclined, and the seatback of each reclining seat is power driven to recline on the seatback hinge, and a footrest assembly of each reclining seat separately mounted on the partition wall in front of the reclining seat, and the footrest assembly contains a footrest and places the footrest in a horizontal footrest position in the same elevation of the cushion of the reclining seat to enhance sitting comfort and to form a bed with both cushion and seatback of the reclining seat, and places the footrest to a higher elevation from the horizontal footrest position and positions close to the cushion to be used as a table, and places the footrest from the horizontal footrest position to a vertical position for storage, and each seating cell on the lower deck has a main ladder assembly, and the main ladder assembly comprises a ladder assembly, a ladder wall, and an electric drive device, and the ladder wall secures its bottom to a floor by the aisle and its top to the ceiling of the lower deck, and the ladder assembly mounts in the ladder wall, and said electric drive device mounts on the ladder wall, and said ladder assembly comprises a pair of vertical footing bars, and several equally spaced ladder steps positioned between the vertical footing bars, and each of the ladder steps has two arms, one on each side, and when the ladder steps is in a horizontal position to become a ladder standing on the floor and face an aisle for climbing, the arms individually hinge their rear ends on the ladder wall, and hinge on the pair of vertical footing bars to create a parallel linkage, and the pair of arms of the top ladder step is driven by the electric drive to rotate the ladder assembly to place the ladder assembly from a storage position to an extended position to become a ladder, permitting passengers to use the ladder to reach the seating cell on the upper deck.
A passenger transportation vehicle has at least a walking aisle along its length, and a lower deck and an upper deck on both sides of each aisle to increase seating area, and each deck height is for sitting only to minimize an increase of a vehicle height, and some sections of the lower deck provide non-reclinable seats to increase the numbers of seats in the passenger transportation vehicle, and both decks are divided into seating sections, along the aisles, and each seating section is divided by the aisles into multiple cells on each of the upper and lower deck, and the seating cells with reclining seats are separated with vertical partition walls, and each seating cell contains one row of the reclining seats mounted on the deck close to the rear partition wall, facing forward, and each reclining seat contains a base frame supported by a pair of horizontally laid linear slides mounted on a footing frame anchored to the deck, a seatback supported by the base frame on a seatback hinge and connected to a stationary structure behind the reclining seat with a pair of tipping bars, enabling to slide on the linear slides when reclining, a cushion supported by the base frame on a cushion hinge, and a pair of links connecting both seatback and cushion to tilt the cushion at different paces when the seatback reclining to achieve sitting comfort and place the cushion horizontally to line up with the seatback when the seatback fully reclined, and the seatback of each reclining seat can be manually reclined on the seatback hinge by releasing a seat locking device, and the footrest assembly of each reclining seat separately mounts on the partition wall in front of the reclining seat, and the footrest assembly contains a footrest and places the footrest in a horizontal footrest position in the same elevation of the cushion of the reclining seat to enhance sitting comfort and to form a bed with both cushion and seatback of the reclining seat, and places the footrest to a higher elevation from the horizontal footrest position and positions close to the cushion to be used as a table, and places the footrest from the horizontal footrest position to a vertical position for storage, and each seating cell on the lower deck has a main ladder assembly, and the main ladder assembly comprises a ladder support frame, a ladder assembly, and a handlebar assembly, and the ladder support frame secures its bottom to a floor by the aisle and its top to the upper deck and supports the ladder assembly, and the handlebar assembly mounts on the top of the ladder support frame and positions at one side of the ladder assembly, and can manually rotate the ladder assembly from a vertical storage position to an extended position to become a ladder, permitting passengers to use the ladder to reach the seating cell on the upper deck.
